(1,66 whom it may concern.

Be it known that we, ALBERT E. SQ UGHERT and CLEMENS OSKAMP, citizens of theUnited States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have jointly invented certain new and useful Improvements in Bakers Trimmers, of which the following is a specification.

It is the object of our invention to provide a new and useful bakers trimmer especially adapted for trimming the edges ofcake and similar articles, so as to provide an even edge therefor and to trim the layers, blanks, .or cake to uniform size.

Our invention is especially useful in trimming the layers of so-called jelly or layer cakes to make the layers of uniform size, so that when placed one above the other they may have an even edge for receiving the icing, coating, or ornamentation thereon, the edges after being trimmed beingvertically straight throughout the various layers placed one above the other, thus providing economy. in

the coating, as there are no spaces to be filled, and giving a smooth finish.

The invention will be readily understood from the following description and claims and from the drawings, in Which Figure 1 is a side elevation of our improved device. Fig. 2 is a horizontal section on the line 00 w of Fig. 1, partly broken away. Fig.

3 is a vertical section on the line 3 y of Fig. 2, showing the table and cutter in adjacentpositions. Fig. 4: is a detail in perspective, showing a portion'of the cutter-ring. Fig. 5 is a detail in central'vertical section, showing a modification of the swiveling connection of the weighting-plate. Fig. 6 is a detail of the cutter-blade in side elevation. Fig. 7 is a side elevation of a modificationof our improved device, showing power connection for automatically raising the table. Fig. 8 is a plan view of the'power mechanism for the same. Fig. 9 is a plan view in detail of the power mechanism, partly broken away, showing the shifting-lever for the clutch; and Fig. 10 is a ver-v tical section of the power mechanism for the table, taken on'the line 2 2 of Fig. 8.

1 is the column or frame, from which brackets 2 3 project.

4 is a table for receiving the layers, blanks,

or cake (shown at 5) to be trimmed. In the form shown the table is capable of being re-r ciprocated by being mounted on a shaft 6, slidable up and down in a bearing 7 on the bracket 3. A lever 8 is pivoted at 9 to a lug 10 on .the column. A link 11 is pivoted to the shaft at 12 and to the lever at 13,, there being preferably a link at, each side of the shaft, taking through an expanded part 14 of hub 23 and merging into an annular flange 24:".

The cutter-frame is secured to a shaft 25, as by means of a set-screw 26. The shaft is journaled in'bearings 27 27, a collar 28 being secured to the shaft for positioning the same. The shaft has'a bevel-pinion 29 secured to it, which meshes with a bevel-wheel 30, journaled on a stud 31 on the bracket 2. A handle 32 on the bevel-wheel, or other means, serves to operate the same. p

A ring 35, to which a cutter-blade 36 is secured, is detachably secured to the cutterframe. Thus the cutter-frame is provided with lugs 37 and the ring with lugs 38, springfingers'39 being secured to the lugs 38 and taking over the lugs 37. One or more of these spring-fingers maybe provided with a catch 40 for preventing accidental removal of the ring from the cutter-frame. A number of these rings maybe provided. The rings are made detachable, so that rings having cutter-blades of different sizes secured thereto may be interchangeably attached to the cutter-frame for cutting the material to different sizes. Thus it may be desirable to trim layers or cakes of, say, eight inches diameter, and to also trim those of diiferentdiameter-say seven inches in diameterand the interchangeability of one size for another. Thus in Fig. 3 we have shown one size of ring and blade in full lines at 35 36 and another in dotted lines at 35' 36. The cutter-blade is preferably made with clearance for readily withdrawing the material without injury after being cut. Thus .60 the lever. A stop 15, preferably adjustable I of these rings permits the ready substitution is provided with an annular shoulder 33 and the ring with a shoulder 34 for centering the ring with relation to the frame.

In order that the blade may pass entirely through the material, we have made the table of such size as to just pass inside the circle of the teeth of the blade of largest diameter. The table is provided with a groove or grooves 43, into which the cutting edges of the blades of smaller diameter take below the surface of the table for passing entirely through the material. The table is provided with ribs 44 for preventing rotation of the material relatively to the table when the cutter enters the same. These ribs may take the form of pins or similar means for retaining the material in position.

A plate 45 is suspended in the cutter-frame and acts as a weight adapted to rest upon the material to be out before the junction of the cutter-blade with the material for holding the material in place. The plate is so suspended that rotation may not be imparted to it by the cutter-frame. Thus it is shown in Fig. 1 as hung on a chain 46, the chain having swiveling connection at.47 with the top of the cage 21 and swiveling connection 48 with the plate. If desired, the suspending connection of the plate may be by means of a rod 49, attached to the plate, the rod being arranged to take into a hollow 50 of the shaft 25, the rod having a knob51 at its upper end and the shaft having a flange 52, against which the knob takes for limiting the downward movement of the weight, the connection between the rod and shaft being loose.

Illustrating the operation, the layeror layers or blanks are placed upon the table. The tableis then raised. The layers, taking against the plate 45, raise the latter, thereby securely positioning the layers on the table. The cutter-frame is turned, the tablebeing continued to be raised meanwhile, thereby trimming the edges of the layers. As soon as the blade has passed through the layers the table is lowered, the weight stopping at its limit of movement, thereby releasing the layers, which may be taken from the table and others put in their place.

If desired, the table and cutter-frame may be caused to relatively approach automatically by connecting the table with the operating mechanism. Referringto Figs. 7 to 10, inclusive, the bevel-gear 30 is cau ed to mesh with a bevel-pinion 29*on a shaft 25. This shaft is journaled in a bearing 27 on a bracket 2, a collar 28 being secured to the shaft above the bearing. The bevel-wheel 30 is secured to a shaft 31, journaled in bearings 55 55 of a yoke 56, extending from the bracket 2 the shaft 31 having a pinion secured to it, which pinion 57 meshes with a gear 58, secured to a shaft 59. The latter has a collar 60 secured to it, which is journaled in bearing 61, the shaft 59 being journaled in a bearing 61, the

' ranged on the shaft 59.

bearings 61 61 being in the yoke 56. Endwise movement of the shaft is prevented by having the gear 58 and an enlarged end 62 on the shaft take against the bearings 61 61. A sleeve 63, forminga spool for the flexible connection hereinafter named, is slidably ar- Between the collar 60 and the end of the sleeve adjacent thereto there is aclutch 64. (shown as a tooth-clutch,) the teeth thereof being respectively on the collar and end of the sleeve. The sleeve has an annular groove 65, into which a pin 66 takes for shifting the sleeve sidenutrdl y. This pin is secured to a lever 67. This lever rests upon a ledge 68 of the yoke 56 and is shiftable upon a pivot 69 on said yoke. A flange 70 extends from the lever. A flexible connection 71, which may be rope or cable, is secured at 72 to the sleeve 63 and takes under the sleeve and above the flange 70, and then takes over and is secured at 73 to the smaller step 74 of a differential pulley 75. A tappet 76 is secured to the cable 71 near its sleeve end, and a tappet 77 is secured to it distanced therefrom. These tappets form contacts taking against the flange of the lever. A flexible connection 78, which may be a rope or cable. has one end thereof secured to the larger step 79 of the differential pulley at 80, the other end being secured to the operating-lever, as by being looped thereabout through an eye 81. A recess 82 is provided in the face of the sleeve 63 for receiving the tappet 76, and a recess 88 is provided in the face of the step 74 of the differential pulley for receiving the tappet 77 when said respective tappets are wound about the sleeve and step, respectively.

In operation the bevel wheel 30 being turned the saw-bladeis revolved, and through pinion 57 and gear 58 and the cables 71 78 and their connections the table is caused to be raised for bringing the layers to be cut across the path of the saw. hen the table has been sufficiently raised, the tappet 77 strikes the flange 70, thereby swinging the lever 67 upon its pivot, moving the sleeve 63 sidewardly and causing disengagement of the clutch 64, permitting the operator to lower the handle 16 for returning the table to initial position. This movement causes the cable upon the sleeve 63 to unwind, and at the proper moment the tappet 76 strikes the flange 70, thereby throwing the clutch 64 into conneetion. This mechanism makes it necessary for the operator to employ but onehand at a time in its operation.

The differential pulley is mounted on a shaft 84, supported in bearings on an arm 86, projecting from the bracket 2.

The layers, blanks, or cakes may be trinnned singly or a number at a time, or the entire cake may be trimmed after it has been filled. These layers when baked usually have oblique edges, according to the form of pan in which they are baked, while after being trimmed the edges are vertically straight, re-

sulting in economy and superior finish of coating. a

The machine is simple, and its operation is rapid.
